1. 源由

为了确保在Jetson Orin平台上继续我们追求的 FPV Geek SDK 推进；奠定一些基础技术的经验和基础；

• Ardupilot开源无人机之Geek SDK讨论
• Ardupilot & OpenIPC & 基于WFB-NG构架分析和数据链路思考
• ArduPilot开源飞控之MAVProxy深入研读系列 - 2蜂群链路

目前，在Jetson Orin 8GB的板子上 jetson-fpv 性能不佳的情况，着实令人着急，呵呵！

2. C/C++环境

Step 1 安装Jetpack 5.1.4 L4T 35.6

参考：《Linux 36.3@Jetson Orin Nano之系统安装》

Step 2 安装依赖组件

$ sudo apt install \
libssl1.1 \
libgstreamer1.0-0 \
gstreamer1.0-tools \
gstreamer1.0-plugins-good \
gstreamer1.0-plugins-bad \
gstreamer1.0-plugins-ugly \
gstreamer1.0-libav \
libgstreamer-plugins-base1.0-dev \
libgstrtspserver-1.0-0 \
libjansson4 \

4. 总结

NVIDIA提供的硬件及其相关库，原厂维护，不开源。应用相关示例代码开源或者提供源代码。

因此，在安装这些性能加速软件时，尤其要注意其版本的对应关系。

若需要进行大型开发，必须关注原厂开发动态以及版本支持情况。进而，公司软件在规划时需要充分考虑进度、里程碑等相应适配。

3. ldd deepstream-app

出现so文件不存在等问题，基本都是链接环节出现的，也就是二进制在编译链接的路径或者库版本不一致的问题。

4.2 二进制help

本能的认为“-i 输入文件”；“-c 配置文件”。实际存在两个问题：

1. 示例代码deepstream-app代码hardcoded一个txt文件
2. 这个txt文件若存在，会导入这个配置文件里面的视频文件

$ deepstream-app --help
Usage:
  deepstream-app [OPTION?] Nvidia DeepStream Demo

Help Options:
  -h, --help                        Show help options
  --help-all                        Show all help options
  --help-gst                        Show GStreamer Options

Application Options:
  -v, --version                     Print DeepStreamSDK version
  -t, --tiledtext                   Display Bounding box labels in tiled mode
  --version-all                     Print DeepStreamSDK and dependencies version
  -c, --cfg-file                    Set the config file
  -i, --input-uri                   Set the input uri (file://stream or rtsp://stream)
